But the change can still cause legacy problems.  A scene file can produce
significantly different results if the pattern is used on a macro scale: for
example, creating a landscape with a height field or an isosurface.  John
Guthkelch's Code Rot is noticeably different.  One may have found just the right
artistic composition in 3.6 by translating the crackle just so.  Such a
composition will be ruined in 3.7, and there doesn't appear to be a way to
update the scene file to obtain the previous result.

The revisions.txt documents changes in the hash, the cache, and memory
management, but there is nothing explicit about any change in the output.

It would be good to document these.

Thanks for all the work you've done.  It is much appreciated.
